All RF Shamans Ltd radio-scientific instruments utilize our in-house designed outdoor cabinet solution that has three layers of EMI/EMC/RFI protection. Not only do our software defined radio-scientific space weather instruments fulfill relevant EMC standard requirements, but exceed the conducted and radiated emission limits by many tens of decibels, rendering our equipment 100% radio silent. This makes possible instrument integration directly below our extremely sensitive radio receive antennas. These instrument cabinet solutions are designed for environmental extremes and so our instruments may be found providing service from Svalbard to Puerto Rico.
🇫🇮 All products designed and manufactured in Finland!


RFsRIO1 is a 20-55 MHz riometer for measuring the impact of solar effects, including D layer absorption.
RFsIONO1 is relocatable ionosonde with compact, broadband HF TX and RX antennas, producing real-time X and O mode ionograms for instant HF communication situational awareness.
RFsTOMO2 is a coherent, dual-band 150/400 MHz satellite tomography receiver for ionospheric studies.



RF Shamans Ltd combines strong expertise in radio technologies with practical capabilities in mechanics and materials. Supported by a broad domestic and international network of specialists, we help turn new ideas into working innovations, ranging from early-stage demonstrators to prototypes and pilot builds.
Our flexible approach allows us to plan, design, and manufacture solutions that match our clients’ requirements, timeline, and budget. We can deliver anything from a simple proof-of-concept demonstrator to a zero-series unit ready for production ramp-up.

RF Shamans’ space telecommunications expertise covers both terrestrial and spaceborne transmission in demanding environments where reliability is essential. In space applications, performance must be achieved under strict power constraints, which makes thermal management critical: high transmission output can generate heat that must be controlled even in vacuum conditions. Maintaining low operating temperatures is directly linked to longer equipment lifespan. These engineering principles apply equally to terrestrial systems.

With extensive experience in radio engineering, RF Shamans Ltd supports customers in solving complex and varied RF challenges. Our services include:
We tailor our engagement to your needs, from focused advisory sessions to deeper research programs, aligned with your objectives and budget. We also provide training, from RF fundamentals to advanced topics, for engineering teams and technical stakeholders.

RF Shamans’ expertise spans a wide technical range from thermal noise to megawatts, from narrowband and coherent techniques to spread spectrum, from hertz to gigahertz-scale applications, and from a nanometer to a quantum. We can analyze, troubleshoot, and mitigate interference across RF systems and operating environments.
Our typical customers work in wireless and optical communications — across research, development, and operational deployments — and value long-term reliability and technical credibility. Our mission is to be a trusted, respected, and well-established partner for RF technology applications.
